Heatless adsorption dryers with pressure dewpoints to -70 °C are suitable when D series refrigerant dryers with pressure dewpoints of + 3 to +7 °C will not meet the requirement.
Before drying, the standard BOGE FP series micro-filter removes any solid and liquid impurities up to 0.01 mm from the compressed air supply.
In the adsorption dryer, the desiccant material adsorbs moisture from the air, resulting in clean, dry compressed air. Pressure dewpoints to -40 °C can be achieved with the standard model.
In parallel with moisture adsorption, regeneration takes place in a second vessel. With type DAZ heatless adsorption dryers, compressed air which has already been dried is used to regenerate the desiccant.
BOGE DACZ series Treatment System
DAZ Adsorption Dryer and DCZ Activated Carbon Adsorber with pre-filter and after-filter
Heatless adsorption dryers with builtin activated carbon adsorbers are installed where the compressed air is required to have a residual oil content down to 0.003 mg/m3 and a pressure dewpoint to -70 °C.
The advantages of using the BOGE DAC treatment system are:
